John Pettie keeps values measured and balanced, a hallmark of tonal restraint. John Pettie keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #825228, is reserved to 10.0% of the surface, where it acts as a focal punctuation. The full value range is 72 units: broad enough to build convincing three-dimensional form. This is the light John Pettie preferred, made measurable.
